This invention relates to hinges and more particularly to hinges for useon doors and the like.

This application is a continuation in part of my prior application forHinges, filed July 25, 1939, Serial No. 286,382.

An object of the invention is to provide a simple, practical andinexpensive article of the character described.

Another object is to provide a hinge for doors and the like whereby thedoor may be swung through a full arc of 180 degrees.

A further object is to provide a hinge as described which is completelyconcealed in closed position.

An additional object is to provide a hinge as described having anadjustable stop.

A further object is to provide a hinge having means for holding the dooropen in any position.

Other objects and advantages will appear and be brought out more fullyin the following specification, reference being had to the accompanyingdrawing, wherein:

Fig. 1 is an elevation view of a hinge embodying my invention as seen inposition in a door and jamb;

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken along the line 33 of Fig. 1;

Fig. 4 is a View similar to Fig. 3 showing the door in open position;

Fig. 5 is a sectional view taken along the line 55 of Fig. 1;

Fig. 6 is a perspective view of one of the hinge members; and

Fig.7 is a perspective view of one of the bearing members.

Referring more particularly to the drawing, I show a door jamb I anddoor I I each of which is suitably recessed to receive a hinge part. Ahinge bracket I2 is secured in the jamb recess as by countersunk screwsaccording to the usual manner, and a similar bracket I3 is secured inthe door recess. The brackets I2 and I3 are identical except for certainparts which are positioned on opposite sides thereof as will be manifesthereinafter. Brackets I2 and I3 have flange portions I4 provided withcountersunk screw holes I for mounting screws l6 and each bracket has aU-shaped portion II, the side portions of which are provided with squareapertures I8 which receive the squared end portions I9 of a bearing pin20. Apertures I8 are nearer one A substantially U-shaped link 2| isprovided with bearing bores 22 adjacent the ends thereof for mounting onbearing pins 26. U portions ii are each provided with a pair of stoplugs 23 which limit the movement of the door as may be seen in Fig. 4.Members l2 and I3 are each provided with a threaded bore 24 in which ispositioned a threaded stop screw 25 which may be provided with a locknut 26. Stop screws 25 are adapted to engage the side portion of member2| for limiting the position of the same in the closed position of thedoor.

Members I2 and I3 are each provided with a plate 21 positioned betweenmember 2| and the upper part of portion ll of the brackets. Plates 2?are each provided with a square aperture 28 to permit portions I9 toextend therethrough. Portions II are each provided with a threaded bore29 in which is located a screw 30, the lower end of which pressesagainst plate 21 such that the tightening of screw 36 will force plate21 against member 2| and serve as a brake for the same.

Screws 30 are preferably provided with fiat heads 3| having a screwdriver slot 32 in the top thereof, and they are preferably provided witha plurality of peripheral notches 33 by which screws may be adjustedafter installation, a hole 34 being formed in each member I2 and I3 topermit a small screw driver to be inserted therethrough and engagenotches 33 whereby the screws may be turned.

The operation of the invention should be clear from the foregoingdescription. With the door in a closed position as shown in Fig. 3, stopscrews 25 engage link 2| and determine the limiting position of thelinkfor this closed position of the door. When the door is opened aquarter of a turn as indicated in full in Fig. 4, bracket I3 will havebeen pivoted degrees carrying with it pin 26 which has been rotated withthe center of bore 22 as an axis. Portions I9 of pin 20 will likewisehave been rotated and the corner edge A of the door will move in alongan arc indicated B which as seen will permit corner A to swing past theface C of the door jamb without interference because of the eccentricposition of portions I 9. When the door is swung to the full openposition, or a swing of degrees as shown by the dotted position in Fig.4, lugs 23 which engage the inner sides of link 2| bracket members eachhaving a U-shaped portion, a link pivotally mounted at its ends in saidU portions of the brackets, one of said brackets having a frictionbearing plate between one of said U portions and said link, and means toadjust the pressure of said plate against said link, said meansincluding a screw in said U portion adjacent said plate provided with aperipherally notched head, said bracket having 10 an aperture adjacentsaid screw head.
